Dynamic jump?

I've been trying to figure out how to change the community 2d platformer controller script to make it so that when the player jumps while standing still, they are allowed to move left and right still.

currently with the given script, if the player was to jump standing still, they would be stuck along the y-axis, and can change rotation, but not position along the x-axis.

 // Does this script currently respond to Input?
 var canControl = true;
 
 // The character will spawn at spawnPoint's position when needed.  This could be changed via a script at runtime to implement, e.g. waypoints/savepoints.
 var spawnPoint : Transform;
 
 class PlatformerControllerMovement {
     // The speed when walking 
     var walkSpeed = 3.0;
     // when pressing "Fire1" button (control) we start running
     var runSpeed = 10.0;
 
     var inAirControlAcceleration = 1.0;
 
     // The gravity for the character
     var gravity = 60.0;
     var maxFallSpeed = 20.0;
 
     // How fast does the character change speeds?  Higher is faster.
     var speedSmoothing = 5.0;
 
     // This controls how fast the graphics of the character "turn around" when the player turns around using the controls.
     var rotationSmoothing = 10.0;
 
     // The current move direction in x-y.  This will always been (1,0,0) or (-1,0,0)
     // The next line, @System.NonSerialized , tells Unity to not serialize the variable or show it in the inspector view.  Very handy for organization!
